Upon arrival of a ’92 Fox coupe we recently acquired, I knew it was in desperate need of a suspension overall. On the lift it went for me to further inspect what I was about to get myself into. Well, this poor car needed more than just shocks and struts. We tackled several front and rear suspension issues with this car to get it back to a normal handling again. This particular article covers my install on Koni's ever-so-popular STR.T, or also referred to as Koni Oranges, into our recently acquired '92 Fox coupe.

I opted for the Koni non-adjustable STR.T shocks and struts because it features a twin-tube design for improved ride quality and better overall handling. They are also a direct replacement for your wore-out factory stuff and even pair perfectly with a set of lowering springs. We sell them as a kit with or without the quad shocks and individually. The Koni STR.T non-adjustable shocks and struts is just the tip of the ice berg when it comes to selecting a kit for your Fox Body Mustang. We offer SEVERAL, and I mean several options all of which can be found at the bottom of the article.

Hey! What’s happening guys? Landan here with Late Model Restoration. Today I’m going to giving you my quick rundown on a popular shock and strut from Koni.

Koni is one of the industry leaders when it comes to high quality, performance suspension components. Since their humble beginning in the 1850s, yes I said the 1850s! Koni has researched and developed world-class shock absorbers for multiple vehicles offering outstanding quality, durability, and performance.

One of the most popular upgrade or replacement shocks and struts for the 87-93 5.0L Mustang is the Koni STR.T shock and strut. Also commonly referred to as, Koni ‘oranges’, these shocks and struts are a perfect budget friendly option for anyone looking to upgrade or replace their worn out factory shocks and struts.

These particular Koni Orange shocks and struts are non-adjustable, but will feature a twin tube design for improved ride quality and better overall handling. They will also be a direct replacement for your factory components and will even pair perfectly with a set of lowering springs. A key note I want to point out on these particular shocks and struts is that they are a low pressure design; so when you unbox them and remove the strap from the body and shaft, you will notice the shaft will not move. No worries, simply pull out on the strut shaft nut and they’ll be ready to install.

You can pick these shocks and struts up individually or already in a kit with or without the quad shock.

This ’92 Fox coupe is in desperate need of a suspension overall, so follow along fellas as I walk you through the easy steps on installing a set of Koni orange shocks and struts. A little disclosure on this one, you will see a few other new parts in the mix as well since we were addressing multiple areas on the car.

To begin installation, place the car on a lift or jack stands. Remove the wheel and then remove the two 17mm bolts securing the brake caliper to the bracket. Remove the caliper from the rotor and tie it out of the way and so that the cable isn’t in a bind. Loosen the two strut to spindle bolts with a 24mm open end wrench on the nut and a 21mm socket on the bolt. Before removing the strut to spindle hardware, secure the lower control arm with a jack. Loosen and remove the sway bar end link hardware. Moving to the engine bay, loosen and remove the strut shaft nut with a 24mm socket.

Remove the strut to spindle hardware and then remove the strut from the car. Remove the factory bump stop from the old strut and transfer it to the new Koni strut.

Re-position your brake caliper over the rotor and re-tighten the previously removed hardware. Fully tighten the strut shaft nut and reassemble your sway bar end link hardware.

Repeat these steps for the other side. Moving to the rear of the car; remove the rear wheels. Support the rear end with a pole jack or jack. Pop the trunk and remove the two trunk carpet retainers and remove the trunk carpet. Remove the four retainers securing the rear trunk liner and remove the liner. Now, remove the two retainers on the passenger side trunk liner; removed the liner from the car. Do the same for the driver’s side. Remove the upper shock bushings.

You may need to use a crescent wrench paired with an open end wrench to loosen the nut. Remove the lower shock hardware with an 18mm socket and 15mm open end wrench. Remove the shocks from the car. Before you install the new Koni shocks, make sure the lower washer and bushing is on the shock. Position it into the car. Loosely tighten the lower shock hardware on both sides.
